Hello everyone,I understand that  bundle manager replaced STM32CubeCLT  with "New STM32Cube for Visual Studio Code extenstion".Is there an option to download the bundles outside VSCode environment for offline installation? Similar to STM32CubeCLT?Rationale here is to use the same toolchain in an headless automated build system with no internet connection.Thanks

Hi,We are currently using STM32H7S7 MCU with display and similar USB C circuit from the developer board.I wanted to connect a Web camera and to be able to display video from the screen.I wanted some help and guidance on where to find the driver?does ST have any driver I can use for getting the USB web camera data. Thanks

BackgroundI have developed firmware for a LoRaWAN device by modifying the LoRaWAN_End_Node example for the B-WL5M-SUBG1 development board, which was extracted from the STM32Cube MCU Package for STM32WL series (v.1.3.0) from ST's website (not through CubeIDE). Based on this, I have further developed a custom PCB containing the STM32WL5MOC and other peripherals (antennae, RTC, LEDs, buzzers, etc.). SituationTo test the custom board, I have flashed the STM32 chip with a simple firmware which toggles the GPIO pins based on button presses - this works as intended. However, when I flash the LoRaWAN_End_Node example for B-WL5M-SUBG1 (downloaded from STM32CubeIDE v.1.18.1) onto the STM32 chip, the device was able to join the LoRaWAN network once, but failed subsequent joins due to a repeated nonce. After num

Hello,I encountered an error when using MCSDK 6.4.1 (Motor Control Software Development Kit 6.4.1) to configure the STM32G431VBT for using the three-resistor internal operational amplifier and performing external differential gain sampling. I would like to ask how to resolve this issue.The following images show my configuration process：

I'm trying to deploy my own AI models on the STM32N6570-DK board. To speed up this process, I directly use the example project "STM32N6-GettingStarted-ImageClassification-main" from the official website. https://www.st.com/en/development-tools/stm32n6-ai.html My own network is generated with ST Edge AI developer Cloud. Code replacement and adjustments have been completed, and the project can be successfully built.When programming the example hex files, everything works fine. However, after programming my own hex files in STM32Programmer, the board either stays at last project or just doesn't react(the lcd goes black). I followed the procedures of programming hex files:1. program ai_fsbl.hex, which is already in the folder

Hello @D.Botelho @mƎALLEm  I had an issue of ThreadX and FDCAN transmit as below. I use the stm32g474 and config a threadx and fdcan with stm32cubemx, so far it works well. but when i add some fdcan transmit code, it comes strangely. the code as below void appThread2(ULONG thread_input) { while(1) { if(fdcan1_RXFlag == 1) { fdcan1_RXFlag = 0; // Clear the receive flag for(int i = 0; i < 8; i++) { fdcan1TxData[i] = fdcan1RxData[i]+1; // Copy received data to transmit buffer } my_FDCAN1_Transmit(fdcan1TxData); // Echo back the received data printf("FDCAN1 Received data: "); for (int i = 0; i < 8; i++) { printf("%02X ", fdcan1RxData[i]); } printf("\r\n"); } // // 发送 0x12 fdcan1TxHeader.Identifier=0x012; fdcan1TxData[0] = (dis_sensor_data1.dis1 >> 0) & 0xff; fdcan1TxData

Hello,I'm currently evaluating STEVAL-ISV020V1 using AN4397 and I'm not reading any voltages from both LDO outputs.Here's my setup:PV_in: 2.6-2.7 V PVBATT: 5v supercapSW1 and SW2 enabledI can confirm that the supercap is charging as STORE shows ~3.9-4V and BATT shows a gradually increasing voltage which reached >3.3V per my last test. SW1 and SW2 are enabled as both LDO_EN pins in CN3 show ~3.9-4V. UVP shows ~1.2-1.3V while EOC ~1V.However, I am not reading any values at all in LDO1 and LDO2 in CN2. Am I missing something in my setup?

Hello everyone,I’m currently deploying multiple models on STM32 using X-CUBE-AI (for example: first using an MLP for a coarse classification “Gas / Not Gas”, then a second model for detailed gas class identification). I’d like to ask about two main topics: Question 1: If multiple models have the same input shape/size, can they “share the same input buffer”?Both models have identical input dimensions, data type (float32), and layout (e.g. 1x60 vector).I’d like to point both models’ ai_buffer.data to the same float in[60], then call ai_*_run sequentially (never in parallel).Is this approach safe/supported in X-CUBE-AI? Could any model overwrite the input buffer during inference (theoretically it shouldn’t, but I’d like to confirm with ST/others) Question 2: What is the best way to

Hello. I'm trying to configure the STM32C011J4M6 to output SPI in Transmit Only Master mode. However, as soon as I turn on SPI in STM32CubeIDE and program it, the uC stops behaving properly. I can't transmit any data and the clock pin stays high with periodic spikes down to ground. My best guess is that this has something to do with the clock pin being assigned to the reset pin.I'm able to program it to toggle GPIO separately, but as soon as I try to change the reset pin to a GPIO, all the GPIO stop toggling and the reset pin does the high with spikes thing. That seems to point to this being a "reassign the reset pin" issue than a SPI issue.Is CubeMX just not disabling the reset pin properly? I don't have anything connected to the uC except the programming SWD clock and data lines, as well as the reset line connected to the programmer.I've never tried to repurpose the reset pin before, but I can't imagine ST would add an unusable SPI peripheral.The o

I am using two  NUCLEO-U385RG-Q boards for I3C communication—one as the Controller (Master) and the other as the Target (Slave). When the Controller’s RX length exceeds the Target’s TX length, after the first call to HAL_I3C_Ctrl_Receive_IT the Controller appears to enter an abnormal state; on the second call to HAL_I3C_Ctrl_Receive_IT, it hangs and an abnormal waveform is observed. After the first call, is there a way to restore the Controller to a normal state? Regarding Target-controlled TX length, please refer to I3C Specification, Section 5.1.2.3.4, which states:In I2C, Read from Target has the issue that only the Controller ends the Read, so the Target has no ability to control the amount of data it returns. In I3C SDR, by contr

Hello everyone,I am working on a custom board with STM32H723VGT6 and LAN8742A but after much troubleshooting, pinging has remained unsuccessful. I am trying to use LwIP without RTOS. I have a NUCLEO-H723ZG that I have been able to successfully ping without RTOS, but when I use the same CubeMX configurations (except the RMII pinout) on my custom board, it does not work. I tried to very closely follow the Ethernet schematic for the NUCLEO-H723ZG, the only main changes I made were the pinout (since I am using VG instead of ZG) and using two ESD protection diodes instead of one for ease of routing. The RMII pinout follows what is presented in CubeMX. Here are the following code modifications I have made, based on the H723ZG example in this repo https://github.com/stm32-hotspot/STM32H7-LwIP-Examples.git:

My timer setup in input capture mode. The ICPrescaler value is set to TIM_ICPSC_DIV2, meaning a capture event will occur on the falling edge of every second pulse.  I need to handle an edge case where I need to "reset" the whole input capture system. If I need to handle a reset in-between the first and second triggers, then the internal prescaler counter will be at 1 when I reset/reconfigure, and then the very next input edge will trigger a capture instead of waiting for the full prescaler count of 2

I am using the STM32U575 on a custom board and see that AN2606 indicates PG10 becomes a SPI MISO output in bootloader mode. I would like to connect this same SPI port to another device with the STM32 in master mode for the user application. In order to avoid contention on this signal, I am hoping that in bootloader mode the SPI MISO output is tri-stated if the associated NSS is negated (high). I have seen a couple of posts that touch on this question but I have not been able to confirm the behavior. For example: https://community.st.com/t5/stm32-mcus-products/spi-pin-states-during-bootloader-detection-phase/m-p/696205 Another post for a different part mentions that the SPI port can be setup to support multiple slaves by tri-stating MISO when not selected, but I don't know if this is the default behavior in bootloader mode for this de

As the title says, the STM32G47 PA9 pin appears to be set high in boot mode opposed to pulled high though a resistor which is states in AN2606. This is becoming a problem because it introduces negative behaviors in our design when we try to reprogram. Is this a known behavior documented elsewhere?I have gotten pretty frustrated when migrating from the STMF3 family to the STMG4 since there are many more pins being pulled or set in one direction or another during boot mode. Is there any way to disable some of these hardware defined communications protocols during the boot loader mode initiated by the BOOT0 pin?

After editing the .IOC file, the code generator will mess up the app_usbx_device.c\MX_USBX_Device_Init() function by placing the codeif (ux_device_stack_initialize(...)right after the variable declarations at the top of the function.Typically, that function call should be around line 151 after 6 other function calls initialize all the pointer variables.The end result is 8 compile warnings about using uninitialized variables.Attempts to wrap the stack initialization in /* USER CODE BEGIN MX_USBX_Device_Init0 */ don't work, and the code generator will just move it to the top of the file anyway.What is the work-around for this?STM32H562VGTxSTM32CubeMX 6.12.0STM32CubeIDE 1.16.0 

Hello guys.I designed a custom board around the STM32F411CEU6. On this board, I have a switch and a screw terminal header, both of which are intended to be used has GPIO inputs. However, with both I've had a struggle working with GPIO inputs and interrupts. Attached is my current code, with my button being located on pin PA0. I intend to use pins PA1 and PA0 as input, with PA1 attached to a mat that activates similar to a switch. What's more confusing is that my display and touch input does indeed work. In fact, even LVGL works on this microcontroller and display. It's only the GPIO interrupts and inputs that I have an issue with. I've also attached a picture of my schematic. Any help is appreciated!/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body *********************************************************
